Answer:
The answer is the 2nd picture: the coccyx bone in humans.
Explanation:
Vestigial Structure:
Structures or anatomical features that do not currently serve a function is the bodily processes of a living organism. Vestiges are believed to have performed active functions in the organism's ancestors throughout its evolutionary history.
Coccyx Bone:
The coccyx or tailbone is an evolutionary remnant of our tree dwelling ancestors. Coccyx has no use in modern humans as we do not need to climb trees.
The coccyx in modern humans serves as an anchor for muscles.
Answer:
B) All DNA molecules will migrate up the gel toward the positive electrode.
Explanation:
Because the DNA has a negative charge - regardless the size-, all DNA molecules will migrate towards the positive electrode, at the top of the gel. This is due to the Coulomb's physic law "force of the interaction between the charges is attractive if the charges have opposite signs".
Instead of migrate down the gel , the DNA will do migrate up the gel (opposite direction).
